NOVELTY - Producing graphene heating wallboard module involves sieving the by-products of the micropowder in the spherical graphite production process and placing in a drying box for drying treatment, and then mixing the dried carbon powder and copper powder uniformly to make a mixed powder. The mixed powder is put in a high-temperature tube furnace, heated for 2-5 hours under the protection of argon gas. The heating temperature is kept at 400-450 degrees C, and then cooled to room temperature and taken out and stored in a vacuum dryer. The 40-50 wt.% plasticizer, 7-10 wt.% lubricant, 7-10 wt.% dispersant, 15-30 wt.% mixed powder are taken and balance is cyclohexanone is taken as a solvent, put the above materials in a tank and mixed and then added the mixed powder to infiltrate after the infiltration is completed. The mixture is placed in a high-speed shearing emulsifier for high-speed dispersion to obtain a mixed heat-generating paint, and dispersion time is controlled within 10-20 minutes. USE - Method of producing graphene heating wallboard module. ADVANTAGE - The method enables to produce graphene heating wallboard module that has good heating efficiency, high strength of the glass fiber cloth, reduces the thickness of the board so that the thickness of the heating wall panel is low, is convenient for installation and laying, has low production cost, and is non-toxic and harmless. DETAILED DESCRIPTION - Producing graphene heating wallboard module involves sieving the by-products of the micropowder in the spherical graphite production process and placing in a drying box for drying treatment, and then mixing the dried carbon powder and copper powder uniformly to make a mixed powder. The mixed powder is put in a high-temperature tube furnace, heated for 2-5 hours under the protection of argon gas. The heating temperature is kept at 400-450 degrees C, and then cooled to room temperature and taken out and stored in a vacuum dryer. The 40-50 wt.% plasticizer, 7-10 wt.% lubricant, 7-10 wt.% dispersant, 15-30 wt.% mixed powder are taken and balance is cyclohexanone is taken as a solvent, put the above materials in a tank and mixed and then added the mixed powder to fully infiltrate after the infiltration is completed. The mixture is placed in a high-speed shearing emulsifier for high-speed dispersion to obtain a mixed heat-generating paint, and the dispersion time is controlled within 10-20 minutes. The glass fiber cloth is cut as the heating base layer according to the wallboard design specifications, and cutting the polystyrene EPS board as the wallboard surface layer. The heating layer is cut, the cut carbon fiber cloth is taken and covered its surface with a 200 mesh screen. The brush is used manually to dip the mixed heat-generating paint after the dispersion treatment and repeatedly brushed the image to ensure the uniform thickness of the coating after painting, removed the screen and waited for the mixed heat-generating paint to solidify. The surface of the glass fiber cloth is spreaded with thermal conductive glue, and then arranged the glass fiber between a pair of polystyrene EPS boards to press and glue to form a heating wallboard. The wires are connected to the edge of the composite sheet, and make the wires contact with the glass fiber cloth inside and is energized to detect the heating of the heating layer of the glass fiber cloth surface layer, and the package is ready for sale after passing the test.
